ButtonBlaster is a compact 48-key keypad based on the Orpheus Pico microcontroller and designed to work with the KMK firmware. The project was inspired by an ergonomic keyboard shown in a video by Joe Scotto. The PCB was custom-designed and paired with a 3D-printed case. It uses Gateron mechanical switches and discrete diodes.

Questions
How big is the ButtonBlaster Keypad PCB?
It measures 284.2 × 90.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ButtonBlaster Keypad use?
105 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ButtonBlaster Keypad KiCad files?
From the MazapanLabs/ButtonBlaster-Keypad repository on GitHub, at the commit this page was made from: the board is PCB/ButtonBlaster-Keypad.kicad_pcb and its schematic PCB/ButtonBlaster-Keypad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ButtonBlaster Keypad design in my own project?
Its repository states no licence, so its author keeps all rights: ask MazapanLabs before reusing the design.
